SL400 SERIES OPERATING-THEATRE LIGHTS

The SL400 series is ideal for surgery, ophthalmology, OBS delivery operation, diagnostics and gynaecology. Also suitable for use within casualty departments and intensive care units.
Outstanding shadow dilution and depth of field
A highly sophisticated reflector with more than 1,000 facets reflects the bulb output through multiple angles creating a virtually shadow-free column of in-focus light.
Minimal laminar-flow interference
The fully sealed light head has been aerodynamically designed to minimize turbulence of laminar-flow sterilization and purification systems.
Accurate colour rendering of cold light beam
The internal optics filter out infrared (heat) and other unwanted wavelengths leaving a cool light beam with a colour temperature close to daylight, so tissue and organ colours are not distorted.
Waterproof membrane control panel
A conveniently placed panel contains on/off controls, a power on indicator, bulb-failure alarms and variable output intensity controls.
Variable focus
The removable, autoclaveable light-head steering handle doubles as a twist-grip focusing control.
Double-walled housing
Ensures that the light-head is robust and stays at a low temperature.
Finely-balanced suspension arms
Multi-jointed, spring-balanced suspension mechanisms permit accurate and stable positioning of the light patch. The arms on ceiling-mounted lights all rotate through 360°.
Video systems and back-up power supplies
CCTV cameras and monitors are available as options on most models, as are wall-mounted battery back-up power supplies.
